Figure 5. Aβ42 fibrils seed the aggregation of Aβ40.

Figure 5

Aggregation of Aβ40 was followed with thioflavin T fluorescence. Three repeats of Aβ40 in the absence of fibril seeds (black traces) and in the presence of 2% Aβ42 fibril seeds (red traces) are shown. Note that the lag time is shortened by the presence of seeds, suggesting that Aβ42 fibril seeds promote the aggregation of Aβ40.
